Although studying theoretical mathematics concepts is an important component of GMAT prep, it is perhaps more important to work numerous practice problems. Consequently, we hope you enjoyed these 50 free practice GMAT problem solving questions with thorough answers. We strongly believe that our proprietary custom-written problems offer a remarkably realistic means of practicing mathematics concepts likely to be tested. Please feel free to download and distribute the accompanying PDF ( another PDF too ), which contains problem solving questions.

This calculator solves quadratic equations. You can solve equations by completing the square or by using quadratic formula. The calculator will write down complete solution. Every step will be explained in detail.

Enter quadratic equation of the form ( ax 2 + bx + c = 0 )

You can enter either integers ( 10 ), decimal numbers( 10.12 ) or FRACTIONS (10/3).

Important: The form will NOT let you enter illegal characters like a, u, %, y, p,. How to input??

Enter expression, e.g. (x^2-y^2)/(x-y) Sample Problem Simplify

Enter expression, e.g. x^2+5x+6 Sample Problem Factor

The solution is where the equations 'meet' or intersect. The red point on the right is the solution of a system of linear equations.

A system of a linear equation and a quadratic equation can have one real solution , two real solutions or no real solutions.
